在疫情背景下物理化学线上教学的建议和反思

Proposals and Reflections on Online Teaching of Physical Chemistry under the Epidemic Background

在疫情背景下,我们教学团队实施了物理化学的"线上教学",通过对学生进行问卷调查,对教学效果进行了反思。本文将对调查问卷反映的问题出发,从增加运用物理化学的理论知识去解释生活中的现象、上课前增加思维导图、教师是否有必要出现在视频中、增加"专题"教学模块、线上课程时间的长短、学生学习的自主性、师生互动性如何增强等多个角度进行讨论,对如何提高物理化学线上授课效果提出建议,最终希望这些建议为其它学科在线教学提供一些借鉴。

Due to epidemic, class teaching could not be carried out normally. Our physical chemistry teaching team had to carry out the online teaching.Physical chemistry was a required subject for pharmacy major, including the first law of thermodynamics, the second law of thermodynamics, phase equilibrium,kinetic chemistry, surface phenomena and so on. Physical chemistry was troublesome for students to learn and teachers to teach, and online teaching was still in an early stage. We greatly expected to summarize and improve the teaching quality of online teaching. Thus, a questionnaire among 170 students who studied online during the epidemic was conducted. According to the questionnaire, 97.6 % of the respondents said it was necessary to make mind map at the begin of online-teaching, 82.9 % of the respondents said it was indispensable for teachers to appear in teaching videos. The questionnaire also showed more than half of them thought the length time of online courses should be set in 30~40 minutes. This paper integrated the problems reflected in the questionnaire, deconstructed the impact of online teaching from the students’ view, then offer some advices. These advices were in the following: increasing applying theoretical knowledge of physical chemistry to explain the phenomenon in life, adding mind map at the begin of online-teaching, whether it was necessary for teachers to appear in the video, adding"special topic" teaching sections, the time length of online courses, students’ learning autonomy, and how to enhance the interactions among teachers and students.Some suggestions are released on how to promote the online teaching quality, enhancing the interactions among students and teachers, improving students’ learning autonomy. In summary, we hope these advices can provide reference for other subjects’ online teaching.
